Monumental Stone
Characteristics
Not all granites are classified by the U.S. Bureau of Mines as suitable for "monumental stone." According to the Bureau's standards for "Class 1" granites, they must meet exacting requirements such as uniform texture and color, freedom from flaws and general suitability for polishing and carving as well as resistance to weathering. Elberton blue-gray granites meet these requirements in every respect. |
